Abstract: A breast implant or tissue expander includes an implant shell having an inner chamber and a tube detachably connected with the implant shell. The tube has a first lumen that is in fluid communication with the inner chamber for adding fluid into the inner chamber to increase the size of said implant shell or for removing fluid from the inner chamber to reduce the size of the implant shell. The tube has a second lumen and one or more lateral openings in fluid communication with the second lumen for draining fluid that collects in tissue surrounding the implant shell. The breast implant has a fluid inlet opening formed in the implant shell, and a valve disposed within the fluid inlet opening. The valve is normally biased into a closed position, and is opened by inserting the distal end of the tube into the fluid inlet opening.
